Abstract

A vehicular lamp fitting according to the present invention comprises: a light guiding body; a first light source; and a second light source, wherein the light guiding body includes a first rod-shaped light guiding portion which guides first light emitted by the first light source, a second rod-shaped light guiding portion which guides second light emitted by the second light source, an intermediate portion which is arranged between the first rod-shaped light guiding portion and the second rod-shaped light guiding portion, a first coupling portion which couples a base end portion side of the first rod-shaped light guiding portion and the intermediate portion together such that a part of the first light, which enters the first rod-shaped light guiding portion through a light entering surface of the first rod-shaped light guiding portion, enters an inside of the intermediate portion.

Claims (45)

1. A vehicular lamp fitting comprising:

a light guiding body;

a first light source; and

a second light source, wherein

the light guiding body includes

a first rod-shaped light guiding portion which guides first light emitted by the first light source,

a second rod-shaped light guiding portion which guides second light emitted by the second light source,

an intermediate portion which is arranged between the first rod-shaped light guiding portion and the second rod-shaped light guiding portion,

a first coupling portion which couples a base end portion side of the first rod-shaped light guiding portion and the intermediate portion together such that a part of the first light, which enters the first rod-shaped light guiding portion through a light entering surface of the first rod-shaped light guiding portion, enters an inside of the intermediate portion, and

a second coupling portion which couples a base end portion side of the second rod-shaped light guiding portion and the intermediate portion together such that a part of the second light, which enters the second rod-shaped light guiding portion through a light entering surface of the second rod-shaped light guiding portion, enters the inside of the intermediate portion,

a decorative member in which a slit-shaped through hole, through which light exiting from the light exiting surface of the intermediate portion passes, is formed,

a light guiding portion which is arranged between the light exiting surface of the intermediate portion and the slit-shaped through hole and which guides the light exiting from the light exiting surface of the intermediate portion to the slit-shaped through hole, and

the intermediate portion includes a light exiting surface from which the first light and the second light, which enter the inside of the intermediate portion, exit.

2. The vehicular lamp fitting according to claim 1 , wherein

the light guiding body includes a third rod-shaped light guiding portion that has a base end portion and a distal end portion, and

the base end portion side of the first rod-shaped light guiding portion and the base end portion side of the third rod-shaped light guiding portion are coupled with each other via a coupling portion.

3. The vehicular lamp fitting according to claim 2 , wherein

the light guiding body includes a fourth rod-shaped light guiding portion that has a base end portion and a distal end portion, and

the base end portion side of the second rod-shaped light guiding portion and the base end portion side of the fourth rod-shaped light guiding portion are coupled with each other via a coupling portion.

4. The vehicular lamp fitting according to claim 3 , wherein

the first rod-shaped light guiding portion includes a first light emitting surface from which the first light, which is guided by the first rod-shaped light guiding portion, exit,

the second rod-shaped light guiding portion includes a second light emitting surface from which the second light, which is guided by the second rod-shaped light guiding portion, exit,

the third rod-shaped light guiding portion includes a third light emitting surface from which light, which is guided by the third rod-shaped light guiding portion, exit,

the fourth rod-shaped light guiding portion includes a fourth light emitting surface from which light, which is guided by the fourth rod-shaped light guiding portion, exit,

a distance between the first light emitting surface and the second light emitting surface, a distance between the first light emitting surface and the fourth light emitting surface, a distance between the third light emitting surface and the second light emitting surface, and a distance between the third light emitting surface and the fourth light emitting surface exceed 75 mm, and

a distance between the first light emitting surface or the third light emitting surface and the light exiting surface of the intermediate portion is set 75 mm or less, and a distance between the second light emitting surface or the fourth light emitting surface and the light exiting surface of the intermediate portion is set 75 mm or less.

5. The vehicular lamp fitting according to claim 4 , further comprising

a third light source, and

a fourth light source, wherein

the third rod-shaped light guiding portion includes a light entering surface on which light from the third light source enters the third rod-shaped light guiding portion, and

the fourth rod-shaped light guiding portion includes a light entering surface on which light from the fourth light source enters the fourth rod-shaped light guiding portion.

6. The vehicular lamp fitting according to claim 2 , wherein

the first rod-shaped light guiding portion includes a first light emitting surface from which the first light, which is guided by the first rod-shaped light guiding portion, exit,

the second rod-shaped light guiding portion includes a second light emitting surface from which the second light, which is guided by the second rod-shaped light guiding portion, exit,

the third rod-shaped light guiding portion includes a third light emitting surface from which light, which is guided by the third rod-shaped light guiding portion, exit,

a distance between the first light emitting surface and the second light emitting surface, and a distance between the third light emitting surface and the second light emitting surface exceed 75 mm, and

a distance between the first light emitting surface or the third light emitting surface and the light exiting surface of the intermediate portion is set 75 mm or less, and a distance between the second light emitting surface and the light exiting surface of the intermediate portion is set 75 mm or less.

7. The vehicular lamp fitting according to claim 6 , further comprising

a third light source, wherein

the third rod-shaped light guiding portion includes a light entering surface on which light from the third light source enters the third rod-shaped light guiding portion.

8. The vehicular lamp fitting according to claim 1 , wherein

the first rod-shaped light guiding portion includes a first light emitting surface from which the first light, which is guided by the first rod-shaped light guiding portion, exit,

the second rod-shaped light guiding portion includes a second light emitting surface from which the second light, which is guided by the second rod-shaped light guiding portion, exit,

a distance between the first light emitting surface and the second light emitting surface exceeds 75 mm, and

a distance between the first light emitting surface and the light exiting surface of the intermediate portion is set 75 mm or less, and a distance between the second light emitting surface and the light exiting surface of the intermediate portion is set 75 mm or less.
